Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (1S,6S)-1,6-Bis((diphenylphosphanyl)oxy)spiro[4.4]nonane (CAS 197252-01-0), a certified reference material (molecular formula C33H34O2P2, MW 524.57 g/mol) for analytical method development and quality control.
Based on its molecular formula C33H34O2P2, (1S,6S)-1,6-Bis((diphenylphosphanyl)oxy)spiro[4.4]nonane contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 524.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
